ところで、特許文献1のような研磨方式の際に研磨部分に向けてウエット式クーラント水を使用する。   By the way, wet type coolant water is used toward the polishing portion in the polishing method as in Patent Document 1.

その際、クーラント水がワーク(ガラス基板)全面或いは広範囲に飛散して、ワークによっては一定範囲以外にクーラント水が付着し、ワークのマスキングなどに悪影響を及ばし、又研磨付近が大幅に汚れて作業性が悪くなるなどの問題が発生した。   At that time, the coolant water scatters over the entire surface of the workpiece (glass substrate) or a wide range, and depending on the workpiece, the coolant water adheres outside a certain range, adversely affects the masking of the workpiece, etc. Problems such as poor workability occurred.

そこで、この発明は、ボックス内でワークの辺を研磨すると共に、研磨部位に噴射するクーラント水のボックス外への飛散を抑止した研磨装置を提供することにある。   SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a polishing apparatus that polishes a side of a workpiece in a box and suppresses splashing of coolant water sprayed to a polishing site outside the box.

上記の課題を解決するために、この発明は、ガラス基板などのワークと、直列状に並ぶと共に、周囲の一面に上記ワークの研磨辺が嵌り込む開口を有する第1ボックス及び第2ボックスとからなり、この第1ボックス内にワークの辺縁を研磨する回転砥石を設け、また上記第1ボックス内に研磨部分にクーラント水を噴射するノズルを設け、さらに上記第1ボックス内に噴射クーラント水を吸引して排出する吸引手段を設け、また上記第2ボックス内にワークに付着したクーラント水の水切りエアナイフを設け、上記ワーク或いは上記第1ボックス及び第2ボックスのいずれか片方を走行手段により走行させるようにした構成を採用する。 In order to solve the above-described problems, the present invention includes a work such as a glass substrate, and a first box and a second box that are arranged in series and have an opening into which a polishing side of the work fits on one surface. becomes, the provided rotary grindstone for polishing the edge of the workpiece in the first box, also in the polishing part in the first box nozzle for injecting coolant water is provided, further a jet coolant water to the first box a suction means for discharging sucked provided, also provided a draining air knife coolant water attached to the work in the second box, to travel by the traveling means any one of the work or the first box and the second box The configuration as described above is adopted.

すると、開口から第1ボックス内に嵌入するワークの辺縁を第1ボックス内の回転砥石により研磨すると共に、ノズルから研磨部位に噴射(供給)したクーラント水を第1ボックス内に吸引し、排出すると共に、ワークに付着したクーラント水を第2ボックス内のエアナイフにより水切りする。 Then, the edge of the workpiece inserted into the first box from the opening is polished by the rotating grindstone in the first box, and the coolant water sprayed (supplied) from the nozzle to the polishing site is sucked into the first box and discharged. At the same time, the coolant water adhering to the workpiece is drained by an air knife in the second box .

以上のように、この発明の研磨装置によれば、周囲一面の開口から第1ボックス内にワークの研磨辺を嵌入すると共に、第1ボックス内の回転砥石によりワークの上記嵌入した辺を研磨すると共に、研磨部位にノズルからクーラント水を噴射するようにしてあるので、クーラント水の飛散を第1ボックスにより受け止めて防止し、第1ボックス内の吸引によって第1ボックス外に流出しようとするクーラント水の略全量の強制的な回収ができる。 As described above, according to the polishing apparatus of the present invention, the polishing side of the workpiece is inserted into the first box from the opening on the entire surface, and the inserted side of the workpiece is polished by the rotating grindstone in the first box. together, since the nozzle to the polishing site are as to inject coolant water, the coolant water to prevent scattering of the coolant water received by the first box, it attempts to flow out to the first box outside by the suction in the first box Can be forcibly recovered.

このため、研磨周囲の飛散クーラント水の汚れがなく、特にワークに対するクーラント水の付着が極力なくするため、ワークのマスキングに悪影響を及ぼすことがないと共に、クーラント水の侵蝕に問題があるワークについてもマスキングを行なったり加工工程の最後にするなど、加工工程の順位などの制約がなくなる。   For this reason, there is no contamination of the coolant around the polishing area, and adhesion of the coolant to the workpiece is minimized, so there is no adverse effect on the masking of the workpiece, and there is also a problem with the corrosion of the coolant. There are no restrictions on the order of processing steps such as masking or the end of the processing step.

また、第2ボックス内に設けてあるエアナイフによってワークに付着したクーラント水の水切りもできる。 Moreover, the coolant water adhering to the workpiece can be drained by an air knife provided in the second box .

以下、この発明の実施の形態を添付図面に基づいて説明する。   Embodiments of the present invention will be described below with reference to the accompanying drawings.

この発明の実施形態では、図1から図4に示すように、ガラス基板などのワークWと、周囲の一面にワークWの研磨辺が嵌り込む開口1を有する第1ボックス2とからなる。 In the embodiment of the present invention, as shown in FIGS. 1 to 4, a work W such as a glass substrate and a first box 2 having an opening 1 into which a polishing edge of the work W is fitted on one surface of the periphery.

上記のワークWは、上側に、第1ボックス2は下側に位置する縦型を示し、第1ボックス2に設ける開口1は、第1ボックス2の上面壁のセンター線上と、第1ボックス2の両端壁の上端中央から下方に向け開放させて設けたが、限定されず、一側にワークWを、他側に第1ボックス2を配置した横型であってもよい。 The above work W to the upper, first box 2 shows a vertical positioned on the lower side, an opening 1 provided in the first box 2, the center line of the first box 2 of the top wall, the first box 2 However, the present invention is not limited thereto, and it may be a horizontal type in which the work W is arranged on one side and the first box 2 is arranged on the other side.

そして、走行手段AによりワークW或いは第1ボックス2のいずれか片方を走行させるようにしてある。 Then, either one of the work W and the first box 2 is caused to travel by the traveling means A.

上記の走行手段Aは、図示の場合二条の水平なレール3と、下面両側に設けてあるスライダ4をレール3にスライド自在に係合した走行体5と、両端を軸承してレール3に沿わせた雄ネジ6と、走行体5に取付けて雄ネジ6にねじ込んだ雌ネジ7と、雄ネジ6を可逆駆動するモーター8とで構成され、走行体5の側面に配置したプレート9の表面に設けてある吸盤10により板面が垂直なワークWの片面を吸引保持してワークWを走行させるようにしてある。   In the illustrated case, the traveling means A includes two horizontal rails 3; a traveling body 5 in which sliders 4 provided on both sides of the lower surface are slidably engaged with the rails 3; The surface of the plate 9 arranged on the side surface of the traveling body 5, which is composed of a male thread 6, a female screw 7 attached to the traveling body 5 and screwed into the male screw 6, and a motor 8 that reversibly drives the male screw 6. The workpiece W is caused to travel by sucking and holding one surface of the workpiece W having a vertical plate surface by the suction cup 10 provided on the surface.

勿論、定位置にワークWを保持(クランプ)して第1ボックス2を進退走行を介し走行させてもよい。 Of course, the first box 2 may be traveled through forward and backward travel while holding (clamping) the workpiece W in place.

そして、走行体5に設けるプレート9も、モーター11により可逆駆動する旋回軸12を取付けて、旋回軸12の旋回によりワークWの辺縁の傾き調整や、研磨縁(辺)の変更など行なう。   The plate 9 provided on the traveling body 5 is also provided with a turning shaft 12 that is reversibly driven by a motor 11, and the turning of the turning shaft 12 adjusts the inclination of the edge of the workpiece W and changes the polishing edge (side).

また、第1ボックス2内には、モーター13により一方向に駆動する回転砥石14が設けてある。 A rotating grindstone 14 that is driven in one direction by a motor 13 is provided in the first box 2.

すると、第1ボックス2の開口1内に辺縁が嵌入してワークWが第1ボックス2の部分を通過する際に、ワークWの辺縁の面に回転砥石14の周面(図示上周面)が接触して研磨する。 Then, when the workpiece W edge is fitted into the first box 2 opening 1 passes through the portion of the first box 2, the peripheral surface of the rotating grinding wheel 14 to the edge surface of the workpiece W (shown on the circumference Surface) contact and polish.

なお、研磨材は、入れ込み機(図示省略)を介しプレート9の吸盤10にワークWを保持させる際に研磨材を見込んで供給するか、或いはプレート9又は第1ボックス2を図示上下方向に昇降装置(図示省略)を作用させて行なえばよい。 Note that the abrasive is supplied in anticipation of the abrasive when holding the workpiece W on the suction cup 10 of the plate 9 via an insertion machine (not shown), or the plate 9 or the first box 2 is moved up and down in the vertical direction in the figure. What is necessary is just to carry out by making an apparatus (illustration omitted) act.

さらに、第1ボックス2内には、回転砥石14による研磨部位にクーラント水を噴射するノズル21が設けてある。 Further, a nozzle 21 for injecting coolant water to a portion polished by the rotating grindstone 14 is provided in the first box 2.

上記のノズル21には、パイプ22をへてクーラント水が圧送されるようになっている。   Coolant water is pumped to the nozzle 21 through the pipe 22.

また、第1ボックス2内は、吸引パイプ23によってクーラント水を吸引するようになっている。 Further, the coolant in the first box 2 is sucked by the suction pipe 23.

上記の吸引パイプ23は、吸引ポンプ(図示省略)に接続され、濾過されてクーラント水を再使用する。   The suction pipe 23 is connected to a suction pump (not shown), filtered, and reuses coolant water.

勿論、吸引パイプ23は、図示の場合、開口1の反対側、すなわち、第1ボックス2の図示底側に接続し、開口1から大気のエアを吸引する。 Of course, in the illustrated case, the suction pipe 23 is connected to the opposite side of the opening 1, that is, the bottom side of the first box 2, and sucks atmospheric air from the opening 1.

その要因は、ノズル21から噴射したクーラント水が開口1から外側、すなわち第1ボックス2外に飛散するのを防止することにある。 The factor is to prevent the coolant water sprayed from the nozzle 21 from splashing outside from the opening 1, that is, outside the first box 2.

なお、図示のように、第1ボックス2の両端壁の開口1下縁に対する回転砥石14の上周縁を極力近づけて(上方への突出度合いを小さくする)、回転砥石14の回転にともなうクーラント水の第1ボックス2外への(開口1から)飛散をなくする。 As shown in the figure, the upper peripheral edge of the rotating grindstone 14 with respect to the lower edge of the opening 1 of the both end walls of the first box 2 is made as close as possible (to reduce the degree of upward protrusion), and the coolant water accompanying the rotation of the rotating grindstone 14 The scattering to the outside of the first box 2 (from the opening 1) is eliminated.

すると、研磨場所の付近がクーラント水で汚れるのを防止すると共に、ワークWに対する一定範囲以外にクーラント水の付着(飛散にともなう)や研磨粉粒の付着による汚れがなくなる。勿論、マスキングに悪影響を及ぼすこともない。   Then, the vicinity of the polishing place is prevented from being contaminated with the coolant water, and the contamination due to the adhesion of the coolant water (according to the scattering) and the adhesion of the abrasive powder particles is eliminated outside the fixed range with respect to the workpiece W. Of course, the masking is not adversely affected.

また、図2及び図5に示すように、第1ボックス2を通過したワークWの研磨ずみ辺を第2ボックス31の開口1と同様の開口32に嵌入させて通過させ、第2ボックス31内に設けてあるエアナイフ33(パイプ34からエアナイフ33の噴射孔にエアを圧送する)によってワークWの両面に付着したクーラント水を吹き飛ばして水切りする。 As shown in FIGS. 2 and 5, the polished side of the workpiece W that has passed through the first box 2 is inserted into and passed through the opening 32 similar to the opening 1 of the second box 31, and is passed through the second box 31. The coolant water adhering to both surfaces of the workpiece W is blown off by the air knife 33 (air is fed from the pipe 34 to the injection hole of the air knife 33).

勿論、第2ボックス31内の水はパイプ35をへて排出する。
勿論、図1、2に示すようにワークWが走行する場合、第1ボックス2、第2ボックス31は走行しないようになっており、逆にすることもある。
Of course , the water in the second box 31 is discharged through the pipe 35.
Of course, as shown in FIGS. 1 and 2, when the workpiece W travels, the first box 2 and the second box 31 do not travel and may be reversed.

すると、クーラント水の付着しない研磨ずみワークWを回収(取り出す)することができる。   Then, it is possible to collect (take out) the polished workpiece W to which the coolant water does not adhere.
